A Philadelphia man who appeared in a YouTube video threatening a top Republican congressman and his family has been found incompetent to stand trial and ordered to undergo psychiatric treatment.

Norman Leboon, 38, will be sent to a federal prison with a mental-health facility for four months, with the goal of treating him so he is capable of standing trial, Assistant U.S. Attorney Robert K. Reed said Tuesday.

Leboon, of the city's Mayfair neighborhood, was charged after the video appeared on the Web last month. In it, he refers to U.S. Rep. Eric Cantor (R., Va.), the Republican House whip, saying: "You're an abomination, you receive my bullets in your office, remember they will be placed in your heads. You and your children are Lucifer's abominations."

The incident received wide attention, coming shortly after the Democratic-controlled Congress had passed President Obama's health-care bill.

Leboon's detention was ordered by U.S. Magistrate Judge Jacob P. Hart after a psychiatric examination. Leboon likely will go to a facility in Butner, N.C., Reed said.

Leboon previously has been diagnosed as suffering from "multiple-personality" disorder and told FBI agents he was "the son of [the] god of Enoch," according to court documents. Enoch is a figure from the book of Genesis.

At the time of his arrest last month, Leboon was wanted on an outstanding city warrant for failing to appear in Municipal Court in July on terroristic threats and assault charges.
